[C320-list] Motor mount change out

[Ken]

Had mine done this past summer.  Concur it is best to do in water so shaft can be properly aligned.
Note that “100” mounts go forward and “75” mounts go aft.  Mechanic reversed them since “aft mounts take most abuse.” The engine ran smooth but, Not being a fan of non-urgent dockside modifications, I checked with Catalina (Warren P) who referred me to the yanmar distributor.  The distribution rep said adamantly that “100”s go forward due to the weight of the engine. I asked for (and he provided) official documentation supporting that argument and the mechanic reinstalled them properly.
Good luck
